I think the best way to start a business generating electricity is to start a business making individual businesses, buildings, and homes more self-sufficient with their electricity needs based on their surroundings rather than thinking in terms of power plants. For example, if the building is near a river, using the river to spin a generator or using windmills in high wind areas, etc. There was actually a pretty cool example of this on the show Dirty Jobs. A guy harvested methane from his animal's poop to power parts of his farm.
To answer your questions.
1. Create your own vertical based on your surroundings. There are really only two ways we currently make electricity, spinning a turbine which then spins a generator, and photovoltaics.
A generator can be made from an electric motor. Figure out how to spin your generator and you are making electricity, or buy some solar panels.
2. Be familiar with Maxwell's equations (these equations explain how both generators and electric motors work), how to read and understand loss charts for wiring, College level circuits, and most importantly safety.
3. Learn basic electrical safety and high voltage electrical safety. High voltage safety is different because of the potential for arcing and it can "grab" you.
